Technology of Moving a Geometric Model Between CAD Packages Using Macros Tools
摘要
The goal is to analyze the existing methods of moving a geometric model and to improve a macroparametric approach for moving a geometric model between specific CAD packages. The subject of the article’s research is the technology of object movement using macro tools. The method is to automate the macro-parametric approach. To transmit parametric information, including the construction tree, a set of standard commands used as a neutral format is defined. A macro file is exchanged that records the sequence of simulation commands or the user’s simulation history. The history of commands that define a high-level dynamic interface is written to a macro file that is used to exchange the static model. The set of commands issued by the CAD developer during the design task is recorded as a simulation history, which implicitly includes the CAD developer’s intent. The results. When analyzing the available methods of moving the geometric model, the degree of accuracy of object transfer was analyzed. The software for implementing the macro parametric approach was developed. The effectiveness of the development can be evaluated by measuring the accuracy of reproducing the geometric model in the source system. That is, achieving maximum correspondence between the construction tree in the input CAD package and the construction tree in the output CAD package. The scientific novelty of the results obtained is as follows: flexible, affordable, and widely scalable software has been developed for transferring the construction tree between different CAD packages. The practical significance. The results of the analysis will make it possible to transfer the geometric model more quickly and accurately.
